Abstract

A method and apparatus for communicating rectangular form binary data over a data bus is disclosed. Prior to being sent, the data is converted by transmit couplers from rectangular form into doublet form, i.e., a single high frequency sinusoidal doublet is created for each transition of the rectangular form data signal. The doublets are applied to the data bus, and receiver couplers connected to the bus change the data from doublet form back into its original rectangular form. Preferably, the data bus is a current mode data bus 31 formed by a pair of twisted wires. Transmit and receive couplers 37 and 39 connected to utilization devices 33 (i.e., devices that originate and/or use the binary data) couple the utilization devices 33 to the twisted wires via coupler transformers 47 and 49. Also, preferably, the data produced and used by the utilization devices 33 is in Manchester biphase form.
